A look back at the history of the American Eugenics movement
will help us learn from flaws of naïve genetic judgment so that we
 may avoid the same mistakes and better use the knowledge,
technology, and refined tools of today to enhance the quality of life. 

The term 'eugenics' was coined by Sir Francis Galton in 1883 to refer to those "good in stock, hereditarily endowed to them with noble quantities."  Other wise stated by Charles Davenport, Galton's U.S. disciple, eugenics was the science of "the improvement of the human race by better breeding."

1. Sir Francis Galton, founder of eugenics The purpose of eugenics, Galton wrote, "is to express the science of improving stock, which is by no means confined to questions of judicious mating, but which, especially in the case of man, takes cognizance of all influences that tend in however remote a degree to give the more suitable races or strains of blood a better chance of prevailing over the less suitable than they otherwise would have had."

The Eugenics movement won substantial recognition in early 20th century America. By 1941, 33 US states had endorsed sterilization policies. The movement was social, political, and scientific. It reflected the fears of many whites that their once-great nation was threatened by demographic and economic change. Their understanding of the principles of genetic inheritance led eugenicists to conclude that genetically defective members of society were rapidly out-reproducing the "normal" members of society at an alarming rate.  These defectives included the "feeble-minded," criminals, the sexually wanton, epileptics, the insane, and non-white races,  and they were passing on their "deleterious" genes at the expense of the "normal." The social cost of such a situation, they feared, would be devastating.

The American Eugenics Society was founded in 1926 by Harry Crampton, Harry H. Laughlin, Madison Grant, and Henry Fairfield Osborn with the express purpose of spearheading the eugenical movement. With a peak membership of around 1,250 in 1930, the AES worked at both the scientific and popular levels, becoming a highly effective organization at disseminating practical and scientific information on genetic health, drawing attention to eugenics, and promoting eugenical research. The history of the Eugenics Movement was chronicled through more than 1,200 materials, primarily from the Eugenics Record Office at Cold Spring Harbor, which, under the direction of Charles Davenport, was the center of American Eugenics research from 1910-1940.

Some used their defects of deformities to provide whatever lifestyle the could. These dwarfs and midgets who worked the in the circus, many other 'freak shows' traveled the country.

The message of eugenics was delivered in ways that appealed directly to "normal" Americans. The American Eugenics Society sponsored "Fitter Family" contests, open to all who chose to participate, using measures of physical appearance, health, behavior, and intelligence to judge which family displayed the greatest potential to produce genetically superior children. Divided into small, medium, and large family categories, as well as couples, the contests were enormously popular.

In his brief definition, Galton laid out all the dimensions that came to characterize eugenics as an ideology and social/political movement during the first half of the twentieth century. People had a firm trust in the methods of selective breeding as an effective means of improving the overall quality of the human species. There was a strong conviction of the power of heredity to directly determine physical, physiological, and mental (including personality) traits in adults. Whether ingrained or newly accepted there was an inherent belief in the inferiority of some races and superiority of others. This view extended to ethnic groups and social classes as well. A faith in the power of rationally applied science to solve pressing social problems. Science was turned to solve the  seemingly intractable problems of urban and labor violence. The science of eugenics attempted to eliminate various forms of mental disease, including manic depression, schizophrenia, and feeblemindedness.

U.S. eugenicists pursued research on the inheritance of a variety of physical, mental, and personality traits. But since they primarily used family-pedigree charts, which were often based on highly subjective and impressionistic data collected from family members, the eugenicists' understanding of genetics was often simplistic and naive. Traits that were studied included alcoholism, pauperism, prostitution, rebelliousness, criminality, feeblemindedness, ability to excel in chess, and even forms of industrial sabotage such as "train wrecking". The eugenicists claimed that each trait was determined by inheriting one or two pairs of  Mendelian genes.

The chart on the right was a student study on inheritance of musical ability. It was believed that there was a specific gene for musical ability and like other traits you would inherit one gene from you mother and one from you father.  The dark circles and squares are 'highly talented musically' while the half shaded shapes are musically inclined. The white shapes do not have musical ability because they did not inherit the gene from either parent.

9. Alfred Binet

Eugenicists also developed close ties with the newly emerging profession of psychometrics, the psychological theory of mental measurement, which was eagerly being employed to develop standardized IQ tests. A Frenchman, the psychologist Alfred Binet, published the first standardized test of human intelligence in 1905. But it was an American, Lewis Terman, a psychology professor at Stanford, who thought to divide a test taker's "mental age," as revealed by that score, by his or her chronological age to derive a number that he called the "intelligence quotient," or IQ.  Terman used this scale and developed the Stanford-Binet IQ test for preschool children. Another prominent
         

American psychometricians was Robert Yerkes the psychologist from Harvard who designed and directed the administration of the Army IQ tests during World War I. The psychometricians believed the mental functions they were measuring were innate, or genetically determined, and therefore that training and education could accomplish only as much for certain social and ethnic groups as the "raw material" of their mental capacity would allow. For their part, eugenicists welcomed the IQ test as an objective and quantitative tool for measuring innate mental ability.

The American IQ promoters scored a great coup during World War I when they persuaded the Army to give IQ tests to 1.7 million inductees. It was the world's first mass administration of an intelligence test, and many of the standardized tests in use today can be traced back to it. The test used the basic technique of measuring intelligence mainly by asking vocabulary questions (synonyms, antonyms, analogies, reading comprehension).  On the basis of IQ tests given to immigrants arriving at Ellis Island, eugenicist Henry H. Goddard "discovered" that more than 80 percent of the Jewish, Hungarian, Polish, Italian, and Russian immigrants were mentally defective, or feebleminded. Goddard believed that such a defect was a condition of the mind or brain which is simply transmitted as a genetic trait. There was no attention paid to other factors that may have had a big affect on the test scores.  Tests were all given in English and under a very strenuous environment to immigrants after traveled across the Atlantic Ocean. It would be impossible to rate real intelligence by using a test that is based on only verbal skills to someone in a language  they are illiterate in.

Eugenics was first embraced politically as a scientific means of halting the rising stream of "defective" immigrants who came to the United States from 1880 to 1914 seeking relief from the economic problems besetting Europe. These new immigrants arrived principally from Eastern and Southern Europe, the Balkans, and Russia and many were Jewish.    These groups were ethnically and culturally distinct from earlier waves of foreigners, such as those in the mid- nineteenth century who had migrated mostly from Anglo-Saxon countries of Western Europe such as Germany, England, Ireland, and Scotland. To many Americans these new immigrants were considered "the dregs of humanity" and  mentally deficient (as confirmed by tests such as those Goddard administered at Ellis Island), socially radical (many had been involved in trade-union activities in Europe), and willing to work for low wages, thus taking jobs away from hard-working Americans.

6. A group of new Immigrants to America

"Some day," said Theodore Roosevelt in 1910, "we will realize that the prime duty, the inescapable duty, of the good citizen of the right type is to leave his or her blood behind him in the world."

A movement known as "progressivism" and its political incarnation, the Progressive Party, whose representative, Theodore Roosevelt, held the presidency from 1901 to 1909. Progressive ideology, was seen as the new and "modern" approach, and hence "progressive" by the standards of the day.

12. Eugenics Text book and 13. An eugenics  course description They called for rational planning and scientific management of every phase of society. Economically they substituted laissez-faire views for an emphasis on state intervention and promoted the use of trained experts in setting economic and social regulatory policies. The movement preached the doctrine of efficiency, which applied cost-benefit analysis and emphasized solving problems at their root, rather than after a crisis has arisen, for example, as in preventive medicine. Eugenics was first embraced politically as a scientific means of halting the rising stream of "defective" immigrants who came to the United States from 1880 to 1914 seeking relief from the economic problems besetting Europe.

14. Birth control book edited by Margaret Sanger

The Eugenics movement quickly became standard education in high school Biology and College. By 1928, the American Genetics Association boasted that there were 376 college courses devoted exclusively to eugenics. High-school biology textbooks followed suit by the mid-1930s, with most containing material favorable to the idea of eugenical control of reproduction. It would thus have been difficult to be an even moderately educated reader in the 1920s or 1930s and not have known, at least in general terms, about the claims of eugenics.

Eugenics has changed the structure of American thought on pregnancy and childbearing. It has established basic conventions for academic work on race and for observational research more generally. Eugenics has provided a very real and deep historical root for resistance to fertility control services. Importantly, eugenics provides us with an example of a program of well-studied practices, scientifically justified and popularly accepted in its time that appears glaringly unethical in hindsight. Thus, it demands from us careful scrutiny of our own research, arguments, political and programmatic policy, by a standard stricter than that of conventionality at the present point in time.

Weegee's hilarious photograph of a showgirl pretending to read "Apes, Men and Morons," written by the Harvard anthropologist Earnest A. Hooton, captured the populist spirit of the eugenics movement.   As you can tell, not every one was enthusiastically for or against the movement. It was the thing to do but here it's just an image, this showgirl might have been the kind of person affected by the movement.

At state and local fairs during the 1920s and 1930s, the AES sponsored lectures and exhibits intended to demonstrate principles of heredity and the menace of unchecked breeding among the unfit (right). "Some people are born to be a burden to the rest," read one sign prominently displayed in the Society's "flashing light exhibit" (left). On this panel, four red lights were set to flash at various intervals, driving home the point of the text. 

While a new child is born in America every 16 seconds, it claimed, every 48 seconds a feeble-minded child is born, every 50 seconds comes a criminal ("Very few normal persons ever go to jail"), but only every seven and a half minutes is a truly creative and capable person born. As for the pocketbook, every 15 seconds, $100 of each taxpayer's money goes to support the mentally and morally defective. The threat to American society, according to eugenicists, was clear: the dangerous and defective were reproducing too quickly, while the normal and advantaged of this nation reproduced too little.

16. A light flashing exhibit used in 1926

Eugenicists argued that if unemployment and crime resulted from the behavior of genetically inadequate persons, then the most rational solution was to prevent those types from being born in the first place. They contended that it was inefficient to allow the biologically degenerate and unfit to reproduce, merely to fill the insane asylums, hospitals, and prisons with defective people that the state must support the rest of their lives.

Such efficiency arguments permeated eugenic literature. Eugenicists pointed out  Ada Juke (pseudonym) as one example. She was a young woman whose impoverished descendants were the subject of one of the first eugenic studies by American sociologist Richard Dugdale in 1874. It would have cost less than $150 in 1790 for the state of New York to have sterilized Ada Juke in 1874 while the estimated cost of caring for her descendants by the 1920s had topped $2 million.

Using the argument for national efficiency, eugenicists successfully lobbied for the passage of a number of state eugenical sterilization   laws in the 1920s and 1930s. Eugenical sterilization was aimed specifically at those individuals in mental or penal institutions who, from family-pedigree analysis, were considered likely to give birth to socially defective children. Sterilization could be ordered any time after  a patient had been examined by a eugenics committee that was composed of a lawyer or family member representing the individual, a judge, and a doctor or other eugenic "expert."   More than 30 states had enacted such compulsory sterilization laws by 1940. Indiana was the first with a eugenical sterilization and it went into effect in 1907. By 1941, more than 60,000 eugenical sterilizations were performed in the United States. Most state sterilization laws were not repealed until after the 1960s.

This group of men were handed these signs given to them by eugenics supporters. From right they read: "I cannot read this sign By what right have I children?" 
"I must drink alcohol to sustain life. Shall I transfer the craving to others?"
"Would the prisons and asylums be filled if my kind had no children?"
(I vote as bankers to myself a.k.a. the  State.)?  "Should I be allowed to propagate?"

18. Carrie Buck pictured on
 the cover of a book written
 about her case in the 1980s

Carrie Buck, a poor white girl born to a poor white mother. After being raped by a member of the family that fostered her, she became pregnant and was sent in disgrace to the Lynchburg Colony, a state institution first set up as a colony for epileptics. There she encountered Dr. Priddy who was an enthusiastic social engineer with a sterilizing program of that had been blocked by a law suit. He wanted to sterilize Carrie to prevent her from having more children. With the help of local politicians and Harry Laughlin they pushed the case of Carrie Buck through to the Supreme Court, hoping to set a precedent that would allow them to continue their work. The expert witness who reported on Carrie's mental state was Laughlin himself, who had never met or talked to her.  'These people,' he wrote, 'belong to the shiftless, ignorant, worthless class of antisocial whites of the South.' Justice Oliver Wendell Holmes agreed. Holmes is quoted stating that "three generations of imbeciles is enough." He had decided that it was constitutionally legal for states to sterilize anyone they decided was eugenically undesirable. "The principle that sustains compulsory vaccination," he elaborated, "is broad enough to cover cutting the fallopian tubes." In other words, the general health of society could be protected at the expense of the rights of individuals.
Calls for restricting immigration grew so dramatically after World War I that in 1921 Albert Johnson, head of the House Committee on Immigration and Naturalization, held a series of hearings preparatory to introducing a bill that would seriously limit immigration, especially from the areas characterized by the new immigrant groups. Any restriction had to appear to be fair, not singling out particular countries or ethnic groups as targets. To make sure that there was some scientific support that would make the restriction seem rational Johnson appointed Laughlin of the Eugenics Records Office as "expert eugenics witness." In this capacity, Laughlin testified twice before the House Committee on Immigration and Naturalization. In 1922, he cited IQ data, Army test results, and family pedigree analyses of institutionalized persons to demonstrate the defective biological nature of the new immigrants. He emphasized that biology, specifically genetics, was crucial in considering such social and political questions as those surrounding immigration, Little or no attention had been paid to the biological aspect of the problem in the past. wpe7.jpg (25496 bytes)

19. Immigrants leaving Ellis Island after passing inspection

Laughlin's point seemed eminently rational. It was inefficient and wasteful of taxpayers' money to care for the world's socially inadequate all their lives. If immigrations was limited they could just be prevented from entering the country in the first place. This was excellent logic to the legislators who worried about the nation's budget and facing staggering social problems of rising unemployment, labor strikes, and inflation.

20. Harry Laughlin (ca. 1929)

In his second official testimony - in 1924, shortly before the immigration bill went to the floor of Congress - Laughlin presented data showing that prisons and mental asylums housed a disproportionate number of immigrants from the very geographic areas that many nativists wanted to restrict. Two committee members, representing largely immigrant constituencies, protested that Laughlin's information was subject to a variety of interpretations.  In response another biologist, Herbert Spencer Jennings from Johns Hopkins University, was called to comment on Laughlin's data and conclusions. Jennings thought Laughlin's analysis of the immigration data was grossly overstated, but Jennings was given only five minutes to testify on the last day of the   hearings, and thus had almost no impact on the subsequent immigration legislation.

The Johnson Act, as it was called, duly passed in 1924   restricting annual immigration from any region to 2 percent of the number of residents from that region already living in the United States as of the 1890 census. Since the vast bulk of the new immigrants had arrived after that date, the Johnson Act, as hoped, restricted these groups most heavily. Immigration from Eastern Europe fell from 75 percent of the total immigration in 1914 to 15 percent after 1924. Laughlin and U.S. eugenicists in general considered the passage of the immigration act a great political triumph.

22. Henry H. Goddard

 

In a study of the "Comparative Social Traits of Various Races" in 1921 (based on a series of questionnaires given to school children), Davenport concluded that Germans ranked highest on qualities such as leadership, humor, generosity, sympathy, and loyalty, while on these same traits Irish, Italian, and in two cases (loyalty and generosity) British people ranked lowest. The Irish ranked highest in "suspiciousness, " while Jewish people ranked highest in "obtrusiveness."
    Davenport assumed, of course, that most if not all such traits were genetically determined, and the social behaviors of not only individual family members, but also whole nations, were genetically fixed at birth.

Henry H. Goddard was a very educated man earning three degrees on of which was a Ph.D. in psychology from Clark University in 1899. He became an advocate of the Eugenicist movement Dr. Goddard believed that feeblemindedness was an inherited trait that could be eliminated all together by sterilizing feeble-minded individuals so they could no longer reproduce.  He was appointed Director of the Research Laboratory at the Vineland Training School and served there for 12 years. During that time he made many breakthroughs in the budding field of mental science. Notable studies include the English translation of the Binet IQ tests, his work with intelligence testing at Ellis Island, his invention of the term "moron," and a best selling book.

Henry Goddard’s book The Kallikak Family: A Study in the Heredity of Feeblemindedness was one of the many best-selling books that led to the enactment of sterilization laws. The book was so popular that it was even considered to be made into a Broadway play.  However, it is interesting to note that this book was almost entirely fiction. The book depicts Martin Kallikak, a Revolutionary War solider, and the descendents of two family lines that he founded. The first line was produced by Martin Kallikak and a virtuous Quaker woman that he married. The descendents of this "wholesome" line were upstanding citizens with no signs of mental retardation. The second line was produced by an illicit affair Martin Kallikak had with a "wayward girl." The result of this illegitimate union lead to generations of criminals, invalids, and feeble-minded individuals or as Goddard called the line "a race of defective degenerates."  

23. Deborah Kallikak

Deborah Kallikak, a member of this line, was one of Goddard’s patients at The Training School. Unfortunately Deborah is documented as being a normal girl who was very crafty and very good with her hands by many others at the training school and by experts looking back at collected data. She was very skilled in dress making and woodworking but lacking in academic areas.   She would have been very able to make a living for herself and she even had many suitors, three specific romantic relationships that were ended by Goddard or the school when ever the secret got out.  The story of her family history had little scientific basis and her diagnosis and treatment were very inaccurate.  As a result of the decisions Goddard made for Deborah and the label she was stuck with she would live in institutions or ‘training schools’ 81 out of her 89 years until she died in 1978.

Goddard claimed that he could recognize feeble-mindedness by sight, and therefore he could determine whether an individual was mentally deficient through as little as a photograph. The validity of this research method is doubtful. Another of Goddard’s methods relied upon interviews. He often determined feeble-mindedness through a second hand account of an individual. This method is clearly flawed. Furthermore, the images Goddard published in the book were doctored to give the descendents of the "degenerate" line a sinister look. Even the name "Kallikak" was a fabrication of Goddard’s: the name is a pseudonym derived from the two Greek words "kallos" (beauty) and "kakos" (bad). As you can see, this was in fact a biased study in which reality had been severely twisted to prove a point.

    Henry Goddard was a biased author who was more concerned with popularizing the Eugenicist movement than conducting a scientific study. Goddard’s erroneous research in conjunction with many others was used as evidence to help pass the state laws that legalized involuntarily sterilization. Later in his career, Henry Goddard withdrew his previous beliefs on the hereditary nature of feeblemindedness and questioned the need for eugenic solutions to the problem of mental deficiency.

Flawed Practices That Could Have Been Modified

There was a difficulty defining traits of the disorders and diseases. Eye and hair color are no problem to pinpoint and define, but epilepsy, intelligence, manic depression, feeblemindedness, and diseases we know as Huntington’s, Downs Syndrome, and Autism may have been thrown into to one category.

There was a tendency to treat complex traits (behaviors) as a single entity coming from one cause or gene. When one of Davenport's friends, a professional psychiatrist, criticized him for lumping complex human behaviors into single categories such as insanity, he dismissed the criticism as being "uninformed." 

Poor survey and statistical methods were used leaving research and studies not scientific but mainly subjective. Family charts would be determined by second hand information not traced back very far.  There was creative use data like the way Laughlin used immigrant statistics from 1921 and population from 1910 to reach the ratios he used as data for the Johnson Act.  

False quantification-a numerical value from IQ test "must be a valid measure". Henry H Goddard gave immigrants test and claimed: 83% Jews, 80% Hung. 79% Italians, 87% Russians, all feebleminded –later retracted, affected many people before that point. 

Social and Environmental influences were neglected when intelligences, behavioral characteristics and other traits were examined. In a 1919 study based on analysis of pedigrees, Davenport claimed that thalassophilia, or "love of the sea," was a sex-linked Mendelian recessive trait only appearing in families of prominent U.S. naval officers. He determined that the trait must be sex-linked since in pedigree after pedigree only males in the various families observed ever became naval officers. They neglected the fact that women were not allowed in the Navy.

25. The family tree of seven generations of boat builders.

The eugenics movement declined somewhat in importance by the mid-1930s, for reasons that are complex and controversial. Most scholars of the subject agree that failure of eugenicists to keep abreast of rapid developments in Mendelian genetics was not, as formerly claimed, a major factor. Similarly, apparent links between American and Nazi eugenics in the 1930s appear to have played only a minor role in bringing eugenics into disrepute.

Many critiques started voicing how a value or measure could not be put on sense of humor, personality, character, self respect and many other characteristics. These and other factors finally prompted the Carnegie Institution to with draw its funding and permanently close down the ERO in December of 1939. 

The older, harsher, more simplistic eugenics of Davenport and his generation declined because it had outlived its political usefulness. With immigration restrictions in place and sterilization laws on the books in many states, the eugenics movement had achieved about as much as could be expected at that time.

26. A drawing of DNA showing detail molecular composition

How close are we today to embracing a modern form of eugenics? Will we in the United States someday soon re-walk those paths of trying to solve our social problems with scientific panaceas? The answer may be yes. A new eugenics movement would, of course, be called by a different name, but an era of similar economic and social conditions and a similar political response. Our current philosophy of "cost-effectiveness" or "the bottom line"- has already arrived.

In the "cutback" atmosphere that dominates our discussions of other social policies, the mood seems similarly exclusionary and bitter. For example, legislation that proposes to limit welfare recipients to five years over a lifetime, the suggestion that welfare mothers with more than two children be given Norplant (an anti-fertility drug), the idea of "three strikes and you're out" (three convictions mean a life sentence), and increasing calls for the death penalty.   It would also be unwise to fail to anticipate how we might respond if we found ourselves in such dire straits. Contemplating our potential for accepting eugenic solutions is particularly important at a time when it might be possible to alter our course.

27. Researchers viewing a DNA gel, working in a la, and micropipetting a solution.

The notion that genes have the power to determine social and personality traits such as criminality and aggressiveness   is becoming popular today in both scientific and lay circles. There have been considerable resources devoted to research on the genetic basis of many such traits. For example, the National Institute of Alcoholism and Alcohol Abuse has allocated $25 million for research on the genetic origins of alcoholism. The National Institute of Mental Health has awarded even larger sums for the study of the genetics of schizophrenia and manic depression.  Other recent studies have attempted to find a specific genetic basis for conditions such as shyness, novelty seeking, risk taking, proneness to anger, impulsivity, attention deficit disorder, and the like. 

Meanwhile, the publicity given to each new or preliminary report on the genetics of human behavioral traits has grown even faster than the research itself. Every major popular magazine - Time, Newsweek, U. S. News and World Report, and the Atlantic Monthly, to name only a few - as well as most major newspapers have carried stories about the newest discovery of a gene for a given disease or trait. Moreover, all the accounts have been presented against the backdrop of the Human Genome Project, whose legitimate discoveries about the location of DNA segments for Huntington's disease and cystic fibrosis, among other conditions, have lent an aura of authenticity and prestige to the general field of human genetics that further validates the more hyperbolic popular reports. One major difference here is that the actual gene of DNA has been located, the proteins it codes for have been identified and the protein's role in expressing that trait is known when a scientist today claims a gene is the cause the trait. There is not as much hand waving and people are not allowed to just claim new evidence with out having proof to back it up.

What can we do to prevent a resurgence of the Eugenics movement? One of the most important weapons we have is the knowledge that it did occur in our recent history. Our understanding of that experience can provide powerful lessons if we are willing to learn from them. To prevent simplistic science can be perverted to socially destructive ends, again.    We also have a far more sophisticated understanding of genetics today than did our counterparts in the 1920s and 1930s. While this knowledge does not guarantee that simplistic claims of a genetic basis for our social behavior will not be put forward, it does mean we can counter such arguments with modern facts. Indeed, researchers have had great difficulty establishing any satisfactory claim that specific genes cause complex human social behaviors. Few of the studies claiming such links have been duplicated and many have been withdrawn after the first flurry of excitement surrounding their publication in professional journals.

One aspect that is now acknowledged is the possibility that genes are not rigid bits of information that invariably lead to the same outcome. Changes in the chemical, physical, and biological conditions can turn genes on or off or change their degree of expression at critical periods in the developmental process. In this respect, the genes affecting human behavioral and personality traits are greatly influenced by environmental input. 

The fact is that today's researchers have had no greater success in rigorously establishing the genetic basis for social behaviors 90 years ago.   There have been great advances for all different kinds of other traits that are already being put into action.

Studies to evaluate environmentally affected traits and those genetically determined, and the ratios of partial traits would be virtually impossible. There is no support to subject ourselves and our children to the rigorously controlled, multigenerational experimentation that would be necessary to begin to tease apart the relative contributions of heredity and environment in the development of special behavioral traits. The environment would need to be controlled to clearly evaluate what influences acted with what intensities at all periods of development. With out that knowledge we have no real way of determining the relative influence of heredity and environment in the interaction.

alone that determine behavior or personality.

30.Will one class create  
 super offspring

Yet another advantage we have at the moment is experience, both in the scientific and lay communities, showing that open opposition to genetic determinist ideas can affect the degree to which they are accepted. Geneticists and other biologists did not stand up publicly to oppose eugenical claims in the 1920s and 1930s the way some of their counterparts are doing today. The claims of Arthur Jensen, Richard Herrnstein, and William Shockley 20 years ago about a genetic basis for racial difference in IQ might have become quietly incorporated into mainstream biology, sociology, psychology, and educational theory had not the scientific claims been disputed publicly by knowledgeable geneticists such as Richard Lewontin and psychologists such as Leon Kamin.

Finally, economic and social conditions affected the support and the publicity awarded to genetically deterministic ideas, then it is clear we must also work to change those conditions and create an economically more humane and egalitarian society. Only by exposing the flaws of naive genetic determinism, while also attending to basic problems in our economic and social system, can we avoid repeating the worst errors of our predecessors.

A "Super" Race?

Some people fear that now that we have the tools to tinker with our genes, we may be tempted to use them to design a "super" race of human beings. As a practical matter, this will probably never be possible. It's one thing to use gene therapy to get rid of an unwanted gene or two. It's a whole lot more to pick and choose the whole range of genes that make an ideal person.

First, the ideal person would have to be determined. Then the different genes that come into play to make that ideal would need to be located and selected. Finally the children would have to be raised so that they grow up to be ideal. Even if these issues were addressed, the political power to make it happen would have to be attained. A grand plan to "improve" the human race would involve the government in personal childbearing and child-rearing choices. This would certainly be opposed by many and difficult to enforce. After looking back at eugenics it is obvious that convincing the public is not the hard part of this process. Determining the ideal and mapping out each gene and all of the filler DNA would be very difficult and beyond today but probably not our lifetime. Personally the hardest part would be to raise the children so they would fully express all of the wonderful genes they have.

31. The technological advances of today will help us rid ourselves of disease, if used carefully

So we may never make a "super" race. But in more limited ways, we may be able to shape our future. The goal is to be able to spare ourselves and our descendants from terrible diseases and disorders while leaving enough variation for the human race to change, adapt and evolve. It will be possible to select some of the traits of our children, and some that are available already. Would you want to? Should these choices be available to everyone? At a certain point there would be a shift of the rich, those able to afford the gene screening and selection, over the poor who can't afford the same opportunities for their children. At a certain point the gene adjustments are not longer just life threatening changes but cosmetic genes a may also be adjusted for the child's benefit.
